      <h1>Implementing A Bulk Update UI</h1>

      <p>This example demos a bulk update UI for a table of data.</p>

      <p>Note that the "server side" implementation is mocked out using mockjax, so you can see the entire
        implementation. Click the "Source Code" tab to see the code.</p>

      <h2>Explanation</h2>

      <ul>
        <li>
          The entire table is wrapped in a <code>form</code> tag, with checkboxes on each row indicating the row id.
        </li>
        <li>
          A drop-down button sits outside the form (not strictly necessary) and includes the form with the
          <a href="/attributes/ic-include.html"><code>ic-include</code></a>
          attribute.  The drop-down button targets the body of the table using the
          <a href="/attributes/ic-target.html"><code>ic-target</code></a>
          attribute and specifies an request indicator via the
          <a href="/attributes/ic-indicator.html"><code>ic-indicator</code></a>
          attribute.
        </li>
        <li>
          The drop-down button has two options, "Active" and "Deactive" which issue posts via
          <a href="/attributes/ic-post-to.html"><code>ic-post-to</code></a>
          to <code>/activate</code> and <code>/deactivate</code> respectively.  Both options inherit all the
          attibutes specified by the parent dropdown button.
        </li>
        <li>
          When the server side handles a post it re-renders all the rows of the table, and applies a class,
          <code>activate</code> or <code>deactivate</code> to a row that is activated or deactivated.  Using
          CSS transitions and the <code>ic-transitioning</code>, we can flash the color of these rows green or red,
          respectively.
        </li>
      </ul>

      <h2>Demo</h2>

      <div>

    This is the initial table.  As with other examples, this table would normally be generated with the same
    template logic defined in the rowsTemplate() below, but is inlined here to make the example more clear.
